In other words, the TeX i-package overwrites the region where all the
texmf trees are kept.
You've expressed yourself in a very misleading fashion.
Is this documented anywhere? I'd like to be able to find out this sort
of thing myself, you see.
And what about the other i-packages?

I find this confusing.
How do you `tell' the TeX i-Package to leave or not leave texmf.local
alone?
Now, it seems at first glance that the sensible way of getting a local
texmf tree accessible to all users is to put it somewhere in:
/usr/local/teTeX
but since an i-installer might mess about with it, it seems to me that a
more sensible approach would be to put it in a directory that no
i-installer would think of looking it.
Or could one create a directory (say)
/usr/local/teTeX/share/texmf.rjmm
and be reasonably sure that no i-installer package would touch it?

So the TeX i-Package deletes some data and adds others. Of course. How
would a maintainer of a TeX installation on a Mac discover what is going
to happen on running an update?

Your guess is as wrong as wrong can be - as I have explained several
times recently. It's a shame you've not believed me, since you're the
person who's supposed to make sure i-installer is safe to use.
What i-installer did was downloaded a large amount of data in multiple
packages. I did not install it - I just grabbed the packages. I then
tried to grab another one, and whoosh! All the previously downloaded
data had been deleted.
There was *NO WARNING AT ALL*. There was no installation. Just
downloads, and data loss.

I'm afraid I do not understand the above paragraph.

What irks me is that you are insistent on not believing what I tell you,
and you insist that what happened was something other than what actually
happened.

Yes, but I have no reason to believe you.

Don't be ridiculous. You know perfectly well that I cannot check your
source code. You also know that your claims about what I did are purely
your invention - frankly, you're trying to harm my reputation.
What I'm telling you is that i-installer threw away a lot of my data.
You have chosen to disbelieve my report. Of course I dare not use your
software - it's not safe.

I think it would be sensible of you to stop insisting on your guess as
to what happened, and pay some attention to my reports.

Yes, but as written above, I had not installed anything at all at the
time i-installer removed *ALL* the downloaded but uninstalled
i-packages.

<sigh> Yes, thank you ever so much for dredging up ancient history. I
must say that helps a great deal.
Your deliberately unhelpful approach last year did indeed succeed in
persuading me to give up in my attempt to install a modern TeX - you did
well there.
Karl Berry said this to me on comp.text.tex recently (I take it you know
the name?)

Hi Rowland,
The purpose of MacTeX is to be easy to install. It is intentional that
there are essentially no questions and customization -- our hope is
that non-expert Mac users will then be able to install TeX. I am not
surprised that an expert like yourself finds it frustrating.

I advise people to read the newsgroup comp.text.tex just to see what I'm
like in a civilised forum full of helpful people; it doesn't seem to
have any of the flamers inhabiting this forum, for example.
Specifically, this thread:

Unlike my experiences on this mailing list, as soon as I requested help
with my MacTeX problem on comp.text.tex, I got instantly helpful
suggestions which I've followed to help me get things sorted out.
What I got here instead was flamage and people telling me not to do what
I wanted to do.
I've had a lot more help from that newsgroup to get me started with
MacTeX than I've had from this mailing list.
What does that say about this forum, I wonder? Perhaps my idea that I'm
being reasonable and I'm getting a lot of really quite unpleasant
replies is spot on - since comp.text.tex has helped me so readily?
[snip]
And perhaps I should post some of Gerben's private emails to me to this
list, just so that people can see how insulting, supercilious, and
unhelpful you are in private?
Or perhaps, instead of dredging up ancient arguments, we could just try
to deal with the issues in front of us now?
Rowland.
